A cyclist has a momentum of 771.9 kg·m/s. If her mass is 93 kg, what is the speed of the cyclist?

A. 8.3 m/s
B. 12.1 m/s
C. 13.2 m/s
D. 4.4 m/s

Answer :

Take 771.9 Kg M/s because that's how fast she is moving and divide it by 93 kg because that is her force pushing down

771.9/93= 8.3

Answer: A. 8.3 M/s

P.s I changed my answer on the last question you asked so change that.

Answer: A (8.3m/s)

Explanation:

Using P = mv

Where p= momentum, m= mass of object , v= velocity.

771.9=93v

Making v subject of formula

V= 771.9/93

V= 8.3m/s
